Question
Explain the classification of qualitative data with a suitable illustration.

Answer

The classification of the data on qualitative variable or an attribute is called qualitative classification.
Illustration : Selecting 50 flowers from a garden, the information on colours of flowers are obtained. It is observed from the data that 12 flowers are of white colour. 10 flowers are of yellow colour. 11 flowers are of red colour, 12 flowers are of pink colour and 15 flowers are of blue colour. This data can be presented in short by a table as follows:
Colour of flower White Yellow Red Pink Blue Total no. of flowers
No. of flowers 12 10 11 12 15 60
  • Here, ‘colour of flower’ is qualitative variable. Therefore. such classification is called the classification of qualitative data.
